Nigerian fintech is one of the most attacked sectors in the country. 💳🛡️🇳🇬

The reason is obvious: Fintech handles real money. A successful attack = direct financial theft.

THE ATTACK SURFACES UNIQUE TO NIGERIAN FINTECH:

💳 Payment Webhook Bypass No Paystack/Flutterwave signature verification. Attacker sends fake charge.success event. Platform credits wallet without real payment. Money withdrawn. Gone.

⚡ Race Conditions Two simultaneous withdrawal requests. Both pass the balance check. Both process against the same balance. User withdraws double their funds.

🔢 Amount Manipulation Amount validated in frontend JavaScript only. Attacker modifies API request directly. Pays ₦100 for a ₦100,000 product.

🔐 Admin Dashboard Weakness Most powerful system in your platform. Often the most poorly protected. No MFA. Weak passwords. No audit logs. One compromised admin = everything compromised.

WHAT CBN EXPECTS IN 2026:

✅ Regular penetration testing ✅ Documented incident response plan ✅ Encryption for all customer financial data ✅ MFA on ALL admin accounts ✅ Transaction monitoring and fraud detection ✅ Business continuity planning ✅ Staff security awareness training ✅ Third-party vendor security assessment

THE SECURITY CONTROLS THAT ACTUALLY WORK:

✅ Webhook signature verification — always ✅ Row-level database locking on balance updates ✅ Server-side amount validation — never trust client ✅ Idempotency keys on all payment operations ✅ Real-time fraud scoring with velocity checks ✅ Device fingerprinting for high-value transactions ✅ Immutable audit logs for all financial operations ✅ Segregation of duties for large transactions
